SPEGIFICATION forming part of Letters Patent No. 755,363, dated March22, 1904.

Application filed January 8, 1904. Serial No. 188,229. (No model.)

To all whom, it may concern.-

Be it known that I, THoMAs M. OoT'rLn, a citizen of the United States,residing at Mountcalm, in thecounty of Hill and State of Texas, haveinvented certain new and useful Improvements in Devices forExterminating Insects on Plants; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings,-making a part of this specification,and to the letters of reference marked thereon.

The object of the present inventionis to provide a convenient andpractical device for applying smoke and fumes to the cotton-plant at anystage of growth, as well as to other plants, whereby any insect whichmay prey upon the plant or its fruits may be effectually exterminated;and it consists in a device constructed substantially as shown in thedrawings and hereinafter described and claimed.

Figure 1 of the drawings is a perspective View of my improved device,showing it connected to the rear end of a cultivator or other wheeledvehicle; Fig. 2, a perspective view of the device with the apronremoved; Fig. 3, a sectional elevation showing the apron in place overthe supporting-frame.

In the accompanying drawings,A represents a portion of the wheel of acultivator or other like vehicle having a supporting-arm B, which ispreferably tubular and projecting from the rear end of the vehicle inany suitable manner. To this arm is connected a clamping-sleeve C,having wings a, through which pass the bolts 6, provided with nuts 0,which engage the screw-threaded ends of the bolts, and by turning thenuts in the proper direction the wings will be brought together andtighten the sleeve around the supporting-arm. and by loosening the nutsthe sleeve can be moved along the arm to any position desired, therebyrendering the sleeve adjustable on the arm and conveniently held in itsadjusted position. The

bolts 6 extend through holes in an anglebrace D, and by the bolts andnuts hereinbefore described the brace is held between the wings of thesleeve C perfectly rigid and stationary.

The outer end of the angle-brace D connects with an angle-brace Ethrough the medium of the bolts CZ and nuts 6, which bolts extendthrough an elongated slot f in the latter-mentioned'brace, and thelongest arm of said brace extends lengthwise of the combustion-chamberor fire box at the front thereof and throughout its length and isriveted or otherwise secured thereto, whereby a reinforce is provided tothe box F, as shown in Fig. 2 of the drawings.

By means of the elongated slot f and the bolts cl and nuts 6 theposition of the fire-box F may be adjusted as circumstances require,said box having a slidable door 9 of any preferred construction, throughwhich the fuel may be deposited in the box, a slidable door it at thebottom of the box, whereby the same may be emptied of its contents,ventilator or register a, and holes 3' for the escape of the smoke.These several features of the combustion-chamber or fire-box to providemeans for supplying the box with fuel, emptying the same, providingventilation to the box to control the process of combustion, and meansfor the escape of the smoke or products of combustion may be variouslymodified or changed in their construction without in any mannerdeparting from the essential features of the invention. V

The upper portion of the box F is provided with a curved hood G, towhich is adjustably connected a curved frame H for supporting the apronI, which may be of cloth or other flexible material, the hood and thefront side of the box being preferably constructed of one and the samepiece of metal, and as the smoke or fumes pass out through the holes itwill be deflected by the apron upon the plants.

One of many means that may be provided for rendering the curved frame Hadjustable resides in the loops k, in which the arms Z of the frameengage and slide, as shown in Fig. 2 of the drawings, the frictionalcontact of the arms with the loops holding the frame in its adj ustedposition.

The adj ustability of the curved frame H enables the support for theapron I to be made larger or smaller, so that a greater or smaller areaof deflecting-surface for the smoke or fumes may be secured when theapron is placed over the frame, as circumstances may require.

The wall of the front of the fire-box F extends some distance beyond theend thereof,

as shown in Fig. 1 of the drawings, so as to give a greater surfacelengthwise to the hood G and also to enable as long an apron as possibleto be used.

In constructing the combustion-chamber or fire-box and the variousattachments thereto it is evident that any suitable material may be usedand any suitable metal for the box and the box may be of any desirablesize and shape as found best adapted to the purpose, as well as makingthe boxes to adapt them to be used on either the right or left of thecultivator or other wheeled vehicle, and any chemicals may be used toproduce the desired smoke or fumes necessary'to the destruction of thepests or insects that may infest or prey upon the plant.

The device as herein constructed is not only very simple, but mostpractical in its results and requiring no experience in its use and willeffectually exterminate all' germs or insects that infest and destroythe cotton or other plant.

Asuitable fuelsuch as wood, coal, or other slow-burning material-may beused in connection with a suitable chemical producing a poison to theinsect, the canvas apron covering the row of plants deflecting thepoisonous fumes over the same and retaining the fumes a sufficient timeto permeate the fruitage and foliage of the plant.

There are many changes or modification in the general construction ofthe fire-box and its attachments that may be made and still come withinthe scope of the invention, and any such changes as would come withinordinary mechanical judgment may be resorted to without departing fromthe spirit of the invention.

Having now fully described my invention, ,5

what I claim as new, and desire to secure by Letters Patent, is

1. A device for destroying insects on plants, comprising a suitablefire-box, means for allowing the smoke or fumes to escape, a curved hoodand a curved frame projecting therefrom and an apron extending over theframe, and suitable means for adjustably connecting the device to awheeled vehicle, substantially as and for the purpose set forth.

2. A device for destroying insects on plants, comprising a suitablefire-box provided with means for the escape of, the smoke or fumes, acurved hood projecting from the fire-box, a suitable frame adjustablyconnected thereto, an apron extending over the frame, and means forconnecting the device to a wheeled vehicle, substantially as and for thepurpose described.

3. A device for destroying insects on plants, comprising a suitablefire-box with means for the escape of the smoke or fumesfan apron and asuitable support therefor, a suitable clamp adapted to be adjustablyconnected to an arm upon a wheeled vehicle, an angle-brace connectingwith the clamp, an angle-brace connected to the fire-box and adj ustablyconnected to the brace connecting with the clamp, substantially as andfor the purpose specified.

f. A device for destroying insects on plants, comprising a suitablefire-box provided with means for the escape of the smoke or fumes, acurved apron extending from the fire-box, a curved frame adjustablyconnected thereto, a suitable apron extending over the frame, and meansfor adj ustably connecting the device to a wheeled vehicle,substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presenceof two witnesses.
